MAX9988ETP+

Overview

The MAX9988ETP+ is a silicon germanium (SiGe) radio frequency amplifier designed for local oscillator buffer and splitter applications. It operates within a frequency range of 1.5 GHz to 2.2 GHz, powered by a single 5 V supply with a typical current consumption of 229 mA. The device provides output power levels between +14 dBm and +20 dBm with a variation of 1 dB. It features 40 dB isolation and functions reliably across an extended temperature range from -40°C to +85°C. Packaged in a TQFN-EP-20 surface-mount format, this component supports general-purpose RF signal distribution tasks.

Feature Summary

• Utilizes SiGe technology for enhanced radio front-end performance
• Provides buffered and split LO signals with consistent amplitude variation
• Offers high isolation characteristics for signal integrity

Applications

• Local oscillator buffering in wireless communication systems
• RF signal splitting in receiver architectures
• General-purpose RF amplification in mixed-signal circuits

Procurement Notes

Verify the end-of-life status before procurement, as the component may be discontinued. Confirm that the TQFN-EP-20 package footprint matches your design requirements. Ensure compatibility with the specified 5 V supply voltage and operating temperature range. Check for available documentation regarding pinout and thermal dissipation guidelines. Validate that the SiGe technology aligns with your system's RF performance needs.

Selection Notes

Select this component when designing RF front-ends requiring precise LO signal distribution. Consider the 1.5 GHz to 2.2 GHz operational bandwidth for suitability. Evaluate the 229 mA current draw against power budget constraints. Assess the TQFN-EP-20 package for space limitations and thermal management. Compare isolation specs against system interference requirements.
